ABSTRACT:
A magnetic-tape apparatus comprises at least one switching device comprising a servo wheel (77; 97) for switching an apparatus function. Further, the apparatus comprises two winding spindles (2, 3) whose lower end portions are each connected to a coaxial winding wheel (4, 5). A reversible drive motor (22), which can be operated at a high and a low torque level, is coupled to the respective winding wheel (4, 5) via a pivotable idler (27) mounted between the winding wheels (4, 5) after the idler has been pivoted to an operating position of the apparatus. In a switching position of the apparatus, the motor (72) is coupled to a coupling device (22). In the switching position of the apparatus this coupling wheel establishes a coupling between the motor (22) and the switching device (77; 97), so that this device is actuated to switch the apparatus function. The motor (22) can actuate the switching device (77; 97) only when it operates at the higher torque level.
